Weather Topic: What is Condensation?

Condensation is the process which creates clouds, and therefore it is a crucial process in the water cycle.
Condensation is the change of matter from a state of gas into a state of liquid, and it happens because water molecules release heat
into the atmosphere and become organized into a more closely packed structure, what we might see as water droplets.

Water is always present in the air around us as a vapor, but it's too small for us to see. When water undergoes the process of
condensation it becomes organized into visible water droplets. You've probably seen condensation happen before on the
surface of a cold drink!

Weather Topic: What is Evaporation?

Evaporation is the process which returns water from the earth back to the atmosphere, and is another crucial process
in the water cycle.

Evaporation is the transformation of liquid into gas, and it happens because molecules are excited
by the application of energy and turn into vapor. In order for water to evaporate it has to be on the surface of a body of water.
